Consider the following stem-and-leaf plot: STEM LEAF 1 | 2 8 5 5 6 | 0 0 1 7 7 | 1 2 9 3 4 4 8 | 9 9 Key: 716 means 76 The value of the quartile coefficient skewness Sa of the data given is 8. When K is a positive integer, what is the value of K? Select the correct option from the dropdown menu to make the statement true. The quartile coefficient of skewness Sa found in the previous part shows that the distribution is not symmetric.

First, we need to understand what a stem-and-leaf plot is. It is a way of organizing data where the first digit(s) of each number is the "stem" and the last digit is the "leaf". For example, the number 123 would have a stem of 12 and a leaf of 3. Show more…

The fewest number of audits is and the most is . The observations are concentrated on the top stems between 12 and 19 audits with other concentrations for 26-29 audits and also for 34-35 audits. The stem-and-leaf plot does not show a clear central tendency, indeed, one could say that the plot is skewed since the density of observations is on the top stems.
